"This non-mainstream self-help lip augmentation device is that air is sucked into the container through the mouth, resulting in a pressure difference between inside and outside. The seemingly plump lips are actually caused by this air pressure difference, which leads to congestion and swelling of the lips, and then the volume increases. " Director Tang Wei, an expert from Shanghai Time Plastic Surgery Hospital, said that at present, the mainstream lip augmentation methods mainly include hyaluronic acid injection and lip autologous fat filling. It is easy to leave bruises on the lips with lip augmentation device, which may affect the girl's appearance, even lead to cheilitis and even some soft tissue necrosis.

In view of these "self-help beauty" patients with lip injuries, Tang Wei said that solutions should be given according to the situation. If it is not too serious, it can be properly iced to reduce swelling, because the skin itself has a recovery function and will soon be naturally repaired; If it is particularly serious and has caused some soft tissue necrosis, it is necessary to remove the necrotic tissue first, and then reconstruct the flap with the surrounding healthy lip tissue.
